Maharashtra State Board Class 5 Maths Solutions Chapter 13 Three Dimensional Objects and Nets Problem Set 51
Nets
Last year we saw that cutting some edges of a box and laying it out flat gives us the net from which it was made.
The two dimensional shape from which a three dimensional object can be made by folding is called the ‘net’ of that object.
Activity :
Draw the nets shown below on card sheet. Cut out the shapes and find out the shapes of the boxes they form.
A five-square net (Pentomino)
In the figure alongside, five squares of the same size are placed together with their sides joined.
Such an arrangement of five squares is called a ‘five-square net’ or a ‘pentomino’.
By folding along the edges of such a five-square net, an open box is formed.
Activity :
Some five-square nets are given below. Draw these nets on a card sheet. Make open boxes from these nets.
Try to find out other five-square nets that can be used to make open boxes.
